TENSION DEVICE FOR SHUTTLES.

To all whom it may concern:

Be it known that I, ALBERT B. GLooR, a

citizen of the United States, residing at Paterson, in the county of Iassaic and State of New Jersey, have invented certain new and useful Improvements in Tension De-, vices for Shuttles, of which the following is a specification. p This invention relates to that class of tension devices in which a thread-controlling member is pivoted to moveback and forth and is normally spring-held in the position for guides thereon to coact with other guides to maintain bends inthe thread. The principal object is to construct the member referred to in a novel way contemplating the ready removal of any one guide from such a part when the guide becomes worn or should it be bent or damaged in any way and the substitution therefore of a new one, or the changing" about of the guides, and also contemplating avoidance of undue cost of manufacture.

In the accompanying drawing,

Figure 1 is a plan, partly in section, of a fragment of a shuttle embodying my inven-v tion;

Figure 2 is a plan of the improved member;

Figure 3 is a plan of said member with the thread-guiding loops removed therefrom; I

Figure at is a front elevation of said mem ber arranged on its pivoting pin, this view being enlarged;

Figure 5 is a view showing theholder or body part in section and one of the loops removed and about to be attached to said holder.

Figure 6 shows a modified form of the improved member; and

Figure 7 is a transverse section of its holder or body part. I

In the shuttle a is arranged the usual series of pins Z) acting as thread guides and coacting with the loops forming the threadguides of my improved pivoted thread controlling member, which is generally designated by the character 0 in Fig. 1. This member includes a body part or holder and a plurality of spring loops interlocked with the holder in the way to be explained.

In Figs. 1 to 5 the body part of the holder is formed of a strip of sheet material, as metal, by bending its lateral edge portions (Z for a considerable part of the length of Specification of Letters Patent.

the piece so as to produce a channel form and bending the edges proper c inwardly toward each other, the portions (Z preferably converging from the longitudinal mid-portion or top f of the piece, and by further folding said edge-portions as to the remainder of the length of the piece over into flatwise contact with the part f, and by still further bending the flattened extremity thus resulting on a crosswise axis so as to produce an eye 9 and leave a depending tail 71 the eye forming the bearing part of the member and adapted to receive the usual pivot pin 2' in the shuttle and the tail It being adapted to have connected thereto the usual elastic band or spring j for holding the member normally at the limit of its pivotal movement illustrated in Fig. 1. Further, the member is formed in-its mid-portion with a v series (extending longitudinally thereof) of holesls equally spaced, and in registry with these holes and in the portions (Z with other holes Z.

The loops m are in the present example U-shaped and are formed by bending flat metal strips into U-shaped form, with the ends n turned outwardly; each loop is elas tie and normally (when detached) has a spread from one leg to the other thereof exceeding the distance between the two sides (Z (Z of the holder.

Each hole 70 is large enough to bodily admit one of the loops and the holes Z large enough to admit the loop-ends n, the fit in each case when the loop is in place being fairly snug so that the loop will be firmly established in the holder.

To attach a loop its legs are sprung together (dotted lines,.Fig. 5) and then first together entered into a hole 70 and then, on relaxing the pressure, allowed to spring ontwardly to permit the ends at to enter holes Z. The loop can be removed by springing its legs together to clear holes Z and then withdrawing it from hole 70.

In Figs. 6 and 7 the loops employed will be'the same as before. But the edge portions 0 of the strip forming the holder are bent up (instead of down, as in Figs. 1 to for the greater part of the length of the piece and have their extreme edges pbent toward each other forming the top wall of the holder, said edge portions being, as in Figs. 1 to 5, folded as to the remainder of the length of the piece flatwise against its bottom Wall g, and the thus flattened end portion being furg aos :05

ther bent to produce the pivoting eye 1' and the tail 8; in the edges 22 are formed opposite notches t to bodily receive the loops, m, and in the edge portions are formed the holes 1) to receive the outwardly bent ends a of the loops.

In both cases, there are .pairs of opposite locking point on the holder arranged in two sets in different planes (in the first form by theset of holes 70 on the one hand and the set'o f holes Z on the other, and in the second form by the set of notches t on the one hand and the set of'holes Q) on the other) with which the loops are engaged so that they are held rigidly and securely in upright position.

It will be understood that the loops are arranged on the holder so as to alternate with the pins 6 and-enter between them when, under tension of the thread A, the device is moved on its pivot.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is: a

1. A controlling member for a tension device of the class described including an elongated holder having locking points arranged in two sets along the same and one above the other, and detachable thread-guiding devices each interlocked with locking points of the two sets.-

2. A controlling member for a tension device of the class described including an elongated holder having locking points arranged "in two sets along the same and one above the other, and detachable thread-guiding devices each having a pair of free end'portions interlocked with a pair of the locking points in each set. i

3. A controlling member for a tension device of the class described including an elongated holder having opposite spaced side walls and having locking points arranged in two sets along the same and oneabove the other and one set in one of the side walls, and detachable thread-guiding devices each receivedbetween said side walls and engaged with looking points of the two sets. 7

i. A controlling member for a tension device of the class described includingan elongated holder having o'pposite spaced side walls and a third wall joining them,and d tachable thread-guiding devices penetrating the third wall and having free ends interlocked with the side walls. 1

In testimony whereof I afiix my signature.
